I have fabspeed exhaust on my car: headers, 200 cel cats, muffler... Sounds amazing, very evil, agressive , brutal, hysterical! It has no valves, on low rpm sounds absolutely normal. Tunnel is the best place to accelerate. Sound is like F1.
First step I made was changing only muffler. Sound was not so good, even worse than the factory sound. I was disappointed very much. But after headers and cats were installed, I got absolutely different car.
For me Fabspeed is one of the best sound I've heard for f430.

I fitted an Agency Power muffler from Vivid last month and I have to say I'm very pleased with it. At low revs it is a bit louder than stock with a much nicer sound than with the vacuum lines plugged on the stock exhaust. But at higher revs with the valves open, bypassing the muffler, it sounds superb. Initially I thought it was too loud but after driving a couple of miles I changed my mine completely and love the sound it makes. At motorway speeds it is quiet enough to easily have a conversation with very little drone.
The exhaust itself looks to be well made with nice welds and has developed a nice colour after a few heat cycles (I never went for the ceramic coating offered by AP).
I didn't bother fitting the remote control for the valves as I'm happy with the stock vacuum system and don't want to be fumbling with a fob if I get pulled over for whatever reason.

I recently replaced my stock exhaust with the oem race exhaust. It is ferrari equipment and Ferrari warranties it. It is basically the cs exhaust. Included is the ecu replacement. The best part apart from te sound is that Ferrari is running a special on it. My dealer fotb replaced mine for just under $4000.

At three times the price. Sound vs quality vs price you cant Nouvalari

Agreed. My take on this was to spend the real cash on fixing the item that actually has a failure problem; the headers. Spare no expense there. On the exhaust, well I could buy 3 Nouvalari systems for the price of any of the other well known brands. At the end of the day, I think we're all buying exhausts for the sound and maybe a little weight reduction and not because we're worried the factory unit is going to fail. Why not get some value out of the switch. Value is hard to come by on these cars!

I agree and had this exhaust on my 360 for several months. Wound up replacing it for other reasons, but totally missed it every day after it came out. The best sound, the best quality construction, and its OEM, so it won't hurt resale (and in fact will help it). $4000 for parts and labor (if that's what you meant) is an excellent deal.
